To all Awhom it may concern Be it known that l, Tiioims A. POWELL, a

citizen o'lI the United States, residing at -Car negie, in the county ofAllegheny and State of Pennsylvania, have invented new and usel'ulImprovements in '\"\vrenclies, oi' which the following is aspecification. i

This invention relates to wrenches, and has lor an object to provide awrench whereby the jaws tl'iereolI can bc quickly adjusted and heldin anell'ee'tive manner.

A further object ol' the present invention" is to provide a quick actingwrenchl which will beextreiiiely simple in construction f composed ol'but few parts, strong, durable Fig. 2 is a longitudinal sectional view,the

jaws of the wrench being open, Fig. 3 is a similar view, the jaws beingclosed. Fig. il is a sectional view on the line 4-4 ol' Fig. 2, llig. 5is a section @i theI line 5 5 ol' Fig. 3. Fig. 6 is a detail sectiontaken on the line (5 6 of Fig. 3.

Referrinfy new more particularly to the drawings, t ere is shown awrench 1 comprising a handle-2 having an angulaily disposed ortion 3 atone end upon which is formed a iixed jaw 4, the jaw being disposed atanangie to the ortion 3 as shown. The handle is provide with alongitudinally disposed grooved portion .5. A sliding jaw G is provided,which has an angularly disposed inner j face upon which is l'ormed aseries ol' translicrctotorc.

versely disposed ratchet teeth 7 adapted to engage correspondinglyshaped teeth 9 upon the inner face ol' the portion 3 ol' thc handle.rl.`lie jaw (j is provided with a sci-rated nut engaging head l0, andthe. jaw 4 is provided with a similar head 11. '.lhe jaw 6 is providedwith a stein 12 disposed in pai-alle relation to the handle 2.- rl`h`estein 12 is forked at one end as shown at 13, and between the arms ofthe fork is shown a pin 14 disposed 1n an elongated slot 15 loi-ined ina linkil of arcuate form.' The link 17 has one end pivotally mounted ina recess 18 formed Iin the handle 2.

A link 19 is provided, which has one end pivotally, mounted in a slot'20 formed in the handle Z and the' other end of this link is disposedin a slot 2 formed in the jaw 6, and. is provided with an elongated slot22 kfor receiving a'transversely disposed pin23; The handle? is providedwith an cyeinemberv 24, andthe stern 12 is provided with an eye member25 the eye member 24 is disposed at one end of the groove 5 and themember 25 is disp` j -d in ii groove 24a in the stem 12, the said eyemembers receiving the ends of a helical spring 2G adapted to hold theteeth 7 and 9 engaged with each other when the jaws are in theiradjusted position; The jaw 6 is provided with a yoke 27 slidably engagedwith the portion 3 of the handle and adapted to guide the stein and thejaw 6 in their movement as is obvious. The handle 2 is provided with alongitudinally extending metallic guard 27 which is preferably of U-formand is thus provided with parallel spaced Walls 2S which receivetherebetween when the wrench is closed the stein 12 as will be seen u onreference lo Fig. 4 of the drawings. W ien thewreuch is iii thisposition, it is obvious that the spring lies entirely in ,the grooves 5and 24 and that all parts of the wrench lie in a compact manner. lheguard is such that the provision thereof also serves as a stop to limitthe movement of the yoke 2, as it will be seen that the yoke engagesportions ol said guard when the loriiier is in a position shown in Figs.l and 2 ol Athe drawing.

lt will be seen that a simple and inexpensive wrench is provided whichmay be inauu-.

factured at a relatively low -iigure and whichl will bc extremelyeffective in use. The device is such that the jaws can he quicklyadjusted without the manipulation of various operative parts sometimesused ratchet t-cetliiiihipted to engage the teeth upon the handle,pivotallymounted links connecting the handle with the sliding iaw, and aspring connecting the sliding jaw with the handle for holdin T the teethof the sldingjaw engaged with the teeth upon the` handle;

"prising a handle, a stern pivotally mounted upon the handle adapted formovement in a parallel plane toward or awayfrorn the same, a Xed jawcarried bythe handle, said handle having a plurality otr ratchet teeth,a' jaw carried by the stem provided with Aratchet teeth adapted toengage the teeth upon the handle, and spring means connect- @ing thestern with said handle.

-' A Wrench of the class described corn- ,prising a handle 'having anoset portion Walls 'adapted to receive therebetween the' stem When thelatter is moved inwardly, a

jaw carried by the stern provided with y2. Awreneh of lthe classdescribed com-k ratchet teeth to engage the teeth upon the offsetportion of the handle, links pivotally connected at their ends tothehandle .and to the stern so that the latter can move in a parallel planewith respect to the former, and spring meansA connecting the stem Withthe handle for yieldingly holding the teeth upon the stein engaged withthe teeth upon the offset portion 'of said handle.

Intestilnony whereof I affix my signature in presence of two Witnesses.
